  1. 1684 - Tire flattening spike, thrown on road.

  2. I agree with Canem, they are also called caltrops.
    1681 - a stand that comes free with a soldering iron.

  3. 1682 - pegboard clips, used to hold a pegboard hook in place

  4. 1683: early autopilot? 'Cause it has a big gyroscope hooked to some sort of actuator. Or possibly a gyro compass, although in that case I would expect it to be mounted on a frame of non-ferrous metal instead of wood.

  5. Correct answers so far:

    1681. Soldering iron rest
    1682. Peg board lock
    1683. Airplane gyroscopic controls
    1684. Caltrops

  6. 1686 could be a hand held lead or slug cutter for typesetting.

  7. 1686 looks like a 'slug cutter' to me! I'll leave the description up to everyone's imagination.

  8. 1685 a station for a watchman's rounds key.

  9. >1686 could be a hand held lead or slug cutter for typesetting

    Good guess! This is correct.
